Check this receipt

This record shows the result and timestamp stored for the call. Recompute the SHA-256 commitment from the saved bytes in your browser; signatures and chain proofs are not checked.

Provenance for every timeline entry

EXECUTED BY ZAMBOZambo ran the tool call itself.
OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.

What is an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

Check this hash yourself

Recompute the SHA-256 commitment in your browser. Open the API v2 JSON response to inspect the machine-readable checks. Signature and chain remain NOT CHECKED unless a real signature verifier or chain proof is supplied. There is no combined “verified” verdict. See the Nostr anchor event on a public viewer. The fingerprint is timestamped outside Zambo too.
